The season will be truncated due to Emily Deschanel's pregnancy, where six episodes will air in 2011, and then go on hiatus for Deschanel's maternity leave. The season will begin a few months after the end of the previous season with Brennan in her third trimester. The season will also introduce a new recurring antagonist, whom executive producer Stephen Nathan describes as "more of a 21st-century, tech-savvy foe" compared the series' past recurring antagonists. The first six episodes will also deal with Booth and Brennan preparing to raise their child.
